This invention relates to improvements in cash registers and likemachines, and more particularly to printing mechanism, and isillustrated as applied to a press-down orkey United States LettersPatent, No. 497,860, issued to Thomas Carney on May 23, 189 3.

l/Vhen adding a feature which requires eX- tensive changes in machinesthatfare being $.10 manufactured, it generally necessitates a redesigning of the machine, which is very expensive and results mostly indelayed manufacturing.

This invention is an improved printer adaptable to be inserted in amachine of the type mentioned, by providing a single actuator for theentire printer, whichactuator is attached to a driven member of themachine, thus eliminating the necessity of redesigning 2c the machine,and the undue delays.

It is, therefore, an object of this invention to provide a printerhaving a common actu- 'ator therefor. i

Another object is to provide a novel sever- 25ing device cooked by theprinter actuator and released by the feeding means at the end of thefeeding stroke.

Still another object is to provide a novel means to retract theimpression hammers 530 from the printer actuator, and an adjustablemeans carried by the actuator to release the retracting means. V

lVith these and incidental objects in view, the invention includescertain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims and apreferred form or embodiment of which is hereinafter described withreference to the drawings which accompany and form a part of thisspecification.

General description Machines ofthe type disclosed herein are providedwith a plurality of groups or denominational sets of keys, mounted onone end of key levers j ournaled intermediate their ends, and supportingat their opposite ends upright key cams having'graduated steps. Thesekey cams are adapted to cooperate with a segment to rock the segment. toposition a typecarrier, and operate totalizer actuators to add thevalue, represented by the operated keys, into a totalizer which isengaged with the actuators during the downward move- 'ment of the outerend of the key levers. The rearwardly extending endof each key lever isadapted to raise an indicator tablet (not shown) to display the value ofthe operated key upon the operation of a key. The usual key couplerextends across the key levers and operates in the, usualand-well knownmanner to coupletogether several keys, so that the:

complete depression of all may be completed by the operation of any oneof them after they have been partially depressed to effect suchcoupling. The weight of the key coupler also acts as a medium to returnthe operated keys to their normal positions.

DETAILED DESCRIPTION Keys and driving mechanism The above mechanism isold and well known in the art, and will be described but briefly.

Key levers (onlyone of which is shown in Fig. 1) arranged indenominational groups are journaled intermediate their ends on auniversal rod 31 extending between and supported by two main side frames32 (only one, the left side frame, being shown).

The rearwardly extending end of each key lever 30 is adapted to raise anindicator tablet (not shown) to display the value of the depressed key.lilach key lever 30 carries near its rearwardly extending end, anupright key cam 33, having a graduated step 34: to cooperate with a rod35, extending between and supported by arms 36 connected by a bail 37,pivoted on a shaft 38, to which a totalizer actuating segment 40 2) issecured. There is one pair of arms 36 for each rod 35, and a segment 40for each denominational group of keys. The segment 40 adds an amountequal to the value of the depressed key into a totalizer (not shown)which is rocked into engagement with the segmenton the downward strokeof the key, and also sets a type carrier.

The operation of the machine by the (16-.

pression of a key, is adapted to give a cam shaft 39 (Figs. 1 and 2) onecomplete rotation, in manner which is old and well known in the art, andtherefore, will be described very briefly.

Extending across the key levers 30 is a key coupler having trunnions 46and 47 projecting from each end thereof and journaled in the main sideframes 32. Projecting from the right-hand side of the key couler 45(Fig. 2) is a stud 48 extending t rough a slot 49 of a rack plate 50which is guided by a stud 51 projecting inwardly from the right sideframe (not shown). The

. rack plate 50 has a rack 52 normally held in mesh, by spring 54, witha pinion 53 secured to the cam shaft 39.

Upon the depression of a key the counterclockwise movement of the keylever 30 rocks the key coupler 45 counter-clockwise, which raises therack plate 50, and the rack 52 rotates the shaft 39 in acounter-clockwise direction.

As the depressed key lever 30 nears the end of its downward movement,the upper end 55 of the left-hand rack contacts a flange 56 of aspring-tensioned arm 57 which tends ink ribbon.

to rock the rack plate 50 clockwise about the stud 51, but is preventedfrom any movement in that direction by an ear 58 projecting from theright-hand rack 52, which ear at this time is riding up in front of aflange 59, projecting inwardly from the right main side frame (notshown).

As the key lever 30 reaches the limit of its downward movement thebottom edge of the travels down the right side of the flange 59,

thus holding the rack 60 in mesh with the pinion 53, which continues torotate the pinion 53 and shaft 39 in a counter-clockwise direction tocomplete the rotation of the shaft 39. Thus, the excursion of the rackplate 50 imparts one complete rotation to the shaft 39. I

As the rack plate 50 reaches its normal position, the car 58 clears thebottom of the flange 59, and the spring 54 rocks the platecounter-clockwise around the stud 51 to disengage the rack 60 from thePinion 53 and engage the rack 52 therewith. Therefore, upon the nextdownward movement of a key, the rack 52 will again rotate the pinion 53and shaft 39 in a counter-clockwise direction, and upon the upwardmovement of said key the rack 60 will complete such rotation.

PRINTER Actudtz'ng means As was previously stated, this inventioncomprises a novel printer, and it is so arranged that it can beassembled in machine of the typ-e disclosed without redesigning'themachine. To drive the printer, a single actuator, operated by the keycoupler, is used.

This printing mechanism will now be described. It includes a printerplate 7 0 (Figs. 1 and 3) suitably mounted in the machine, which plateforms a support for a record printing hammer 71, type carriers 72, areceipt printing hammer 73, a second group of type carriers 7 4, a pairof feed rollers 7), a scissor operating knife 76 (Fig. 4; to sever theprinted receipt, and an All of the above mentioned parts are driven by acommon actuator 7 7 (Figs. 1 and 3) mounted on the key coupler 45 toreceive one excursion upon each operation of the machine, firstcounter-clockwise, and then in a clockwise direction.

Detail feed As the key coupler't5 receives its counterclockwisemoveinent by the depression of a key, the common actuator 77raises a feeding arm 7 8 (Figs. 1 and 3) supported on a stud 79projecting laterally from the actuator 77. The upper end of the arm 78cooperates with a ratchet 30 secured. to the side of a detail paperreceiving roll 81 upon which the paper 82 is ,wound, it being.unwoundfrom a supply roll 83 jo'urnaled on'a stud projecting fromthe'printer frame '70. The paper passes under studs 69 and between theprinting platen and type carriers, on its travel fror thesupply roll83to the receiving'roll 81. 7 As the com mon actuator 77 receives itscounter-clockwise movement, the feeding arm 78 advances the receivingroll 81 one tooth space to position a blank portion of the paper 82 atthe printing line to receive the impression- It can be noticed byreferring to Fig. 3, that the feeding arm 78 has an elongated openingwhich receives the stud 79. The movement the key coupler 45 ii'nparts tothe common actuator 77 is greater than the movement required to advancethe receiving roll 81 one step, and during the first part or themovement of the actuator 77, the stud 79 moves idly in the slot of thefeeding arm 78. A spring 84 connected to the upper end of the feedingarm 7 8, normally tends to force the feedin arm slightly in an upwarddirection to position the feeding arm '7 8 so that the stud 79 is. inthe lower part of the slot. The spring 84 also holds the feeding arm incooperative relation with the ratchet 80. A spring tensioned retainingpawl 85 pivoted on a stud projecting from the printer frame 70,cooperates with the ratchet 80 to prevent any retrograde movementthereof.

Type setting The means for and manner of setting the type carriers 72and 74; will now be described. Upon depression of an amountkey, thegraduated step 3% of thekey cam 33, on its upward movement, picks up theuniversal rod 35 for the denominational group to which the operated keybelongs, and rocks the previously mentioned segment 40 a distanceaccording to the value of the depressed key. The movement of eachsegment 40 is transferred by a pinion and a tube 91 surrounding a shaft92, to its type carrier 72 (F 2 and The pinion 90 is secured to one endof the tube 91, and the type carrier 72 is secured to the opposite endof the tube 91. The type carriers 72 print on the record strip 82.

The type carriers 74 from which the receipt is printed, are alsoadjusted through the same type carriers 72 is transmitted through thegearing ust described to the type carriers 74;

operating means for the Retreading and v hammers The common actuator 77also retracts the impression hammers. Upon counter-clockwise movement ofthe actuator, a driving dog (Fig. 3) pivoted on the common actuator .77cooperates with a hammer operating arm 101, pivoted on a hammersupporting stud '102 projecting through the printer plate 70,

to rock the -arm 101 clockwise against the tension of a strong spring103 connected to the hammer operating arm 101 and to astud 104: on theprinter frame 70.

Connected to the hammer operating arm 101 is a second arm 105,supporting one end of a hammer retracting link 106. The opposite end ofthe link 106 has a slot 108 cmbracing a stud 107- on the hammer 71. Asthe hammer operating arm 101 is rocked clockwise bythe dog 100, thesecond arm moves the retracting link 106 toward the right in thedirection of its length, whereupon a spring 109 rocks the hammer 71 incounter-clockwise direction about its pivot 110.

The clockwise movement of the hammer operating arm 101 also retractsthereceipt printing hammer 73 (Fig.

.A stud on the arm 101 enters a slot 116 of a short arm 117 pivoted on areceipt hammer arm 118. The arm 118 is of yoke formation and is pivotedon the stud 102 and on a stud 119 (Fig. 10) projecting from theauxiliary frame 96 and in axial alignment with the stud 102.

Arms 120 and 121 (Figs. 5 and 10) supportedby the hammeroperating arm118 are hooked at their upper ends to cooperate with hooks 122 and 123of plates 12 1 and 125. The plate 124's guided by studs 126 on theprinter frame 7 0 and the plate 125 is likewise guided by studs 127(only one of which is shown in Fig. 10) projecting from aprinter cap128. Studs 126 and127 are in axial alignment. Arms 129 and 130 (Figs. 5and 10), con ,nected by a yoke 132, are pivot-ed on a stud 131supportedby the printer frame 70 and the. printer cap 128. A spring 133connected to a stud 13 1 on the arm 129 holds a finger 15 1 in contactwith the uppermost hook on the plate 12 1, thus maintaining the hook 122in contact with the hook formed on the arm 120. The arm 130 also has afinger like 154, which is held in contact with the upper book of theplate 125 to maintain'the hook are 123 (Fig. 10) in contact with thehook of the arm 121.

Secured to the plates 124 and 125 are plates 135 and 136 (Fig. 10)respectively, connected by a yoke 137 which supports the various platensof the receipt printing hammer 73 (Fig. 5), such as the amount platen156, an electro platen 157, and a consecutive number platen 158.

From the above description it will be clear that as. the hammeroperating arm 101 is moved clockwise by the driving dog 100, the studrocks the hammer arm 118 and raises the arms 120 and 121.

The arms 120 and 121 are guided in recesses cut in opposite sides of abracket 138 (Fig. 5) which supports the electro. One edge 139 of eachrecess prevents the hooks of the arms 120 and 121 from being moved outof the plane of the hooks 122 and 123 of the plates 124 and 125. Theplates 124 and 125 do not move upwardly under influence of the spring133 when the arms 120 and 121 are raised, since the plate 124 abuts aprojection of a paper support plate 141 mounted on the printer frame 70.

As the common actuator 77 reaches the limit of its countenclockwisemovement, which is at the same time the depressed key reaches the limitof its downward movement, the driving dog 100 is disengaged from thehammer operating arm 101 by an adjustable trip plate 145 carried by theactuator 77, to permit the impression hammers to make an impression onthe record strip and the receipt.

A spring 153 (Fig. 3) normally holds the nose of the driving dog 100 incooperative re lation with the hammer operating arm 101. As the actuator77 moves counter-clockwise, carrying with it the dog 100, the latter isrocked slowly clockwise about its pivot by the spring 153 to maintainits cooperative relation with the hammer operating arm 101, until aprojection 146 of the driving dog 100 contacts the surface 144 of thetrip plate 145.

As the common actuator 7 7 nears the limit of its counter-clockwisemovement, the projection 146 blocks further clockwise movement of thedriving dog 100, and causes the same to move in a path concentric withthe pivot trunnion 46 of the key coupler.

The driving dog 100 travels in this path of movement, concentric withthe pivot trunnion 46, until the actuator 77 reaches the limit of itscounter-clockwise movement, at which time the dog 100 escapes from thearm 101, whereupon the spring 103 gives the arm 101 a quickcounter-clockwise movement until the same is arrested by a stop stud 147on the printer frame 70.

The quick clockwise movement of the hammer operating arm 101, andconsequently of the arm 105, moves the link 106 to its normal position,and the latter effects a rapid clockwise movement of the hammer 71.

This rapid movement imparted to the hammer 71, due to a weight 148carried thereby, carries the hammer beyond its normal position, the stud107 of the hammer traveling in the slot 108 of the link 106, until theplaten 149 drives the record strip against the type carriers 72 and anink ribbon 270, thus causing an impression to be made on the recordstrip 82. The spring 109 then restores the hammer 71 and platen 149 totheir normal positions shown in Fig. 3.

The impression is taken on the receipt paper, by the quick clockwisemovement of the hammer operating arm 101 at the same time the hammer 71is operated to make the impression on the record strip.

It will be recalled that the receipt hammer arm 118 (Figs. 5 and 10) wasrocked clockwise to raise the arms 120 and 121. The quickcounter-clockwise movement of the hammer operating arm 101 rocks thehammer arm 118 rapidly in counter-clockwise direction to lower the arms120 and 121.

The momentum of the arm 118, aided by a weight 150 thereon, issufiicient to carry the arms 120 and 121 past their normal positions,the slot 116 of the arm 117 permitting such additional movement of thearm 118 beyond its normal position.

As'can be seen from Fig. 5, the lowering of the hook arms 120 and 121past their normal positions also lowers the plates 124 and 125, whichlowers the plates 135 and 136 and the yoke 137, whereupon the plat-ens156, 151 and 158 force the check or receipt strip 151 against the typecarriers to make an impression. The ink ribbon 270 makes the impressionslegible.

After the impression has been so made, the spring 133 restores theplatens and their supporting means to their normal positions shown inFig. 5.

' The trip plate 145 is pivoted on a stud 142 (Fig. 3) on the actuator77 and held in place by an adjusting screw 143.

By a close examination of the trip plate 145, it can be seen that thesurface 144, which cooperates with the projection 146, is not concentricwith the pivot 142 of the trip plate. Therefore, by shifting the tripplate 145 in either direction, a higher or lower surface can be broughtbeneath the projection 146 to vary the time of escapement of the drivingdog 100 from the hammer operating arm 10 Ohecic strip feed After thereceipt has been printed by the mechanism just described, operated bythe common actuator 77, feed rollers 75 and (Figs. 1, 5 and 7), alsooperated by the common actuator, advance the printed receipt onto areceipt table 152 (see also Fig. 11), after which it is severed by ascissor operating knife, to be hereinafter described.

There are two feed rollers 75 secured to a short shaft 161 journaled inarms 162 and 163 pivoted on a rod 164 mountedbetween the printer cap 128and the printer frame- 7 0. There are also two rollers 165 looselymounted on a shaft166 journaled in the printer frame and the a'ukiliaryframe 96. The rollers act. as tension and ejector roller s, and arenormally held away from the'rollers 165 by springs 167 and 169 connectedto the arms 162 and 163 respectively (Figs. 5 and 7) The arm 162 has arearwardly extending arm 171 (Fig. 7) carryinga stud 170 projecting intoa notch of one arm 172 of a bell crank 173 pivoted on the shaft 38. V

A stud 174 projecting from asecond arm 17 5 of the bell crank 173 isheld in contact with a finger 176 of a tension operating bell crank 180by a strong spring 177. A roller 178 on one arm 179 of the bell crank180 is held in contact with the periphery of the tensi on cam 168 by thespring 177. The spring 177, being connected tothe arms 176 and 179, hasthe dual function of maintaining the contact between the roller 17 4andarm 176, and

between the roller 178 and cam 168. Due to the fact that the spring 177is strong enough to overcome both of the springs 167 and 169,

it en ables the connections'from the roller 178 to the arm 171 to limitthe clockwise movement of the arms 162 and 163 under influence of theirsprings 167 and 169' 1 I 'i The combination tension and ejector rollers75 are rotated to feed the printed receipt from the machine, by asegment 190 (Fig. 7)

- pivotedon the rod 164.

Secured to the shaft 161, to which the tension and ejector rollers '75are fastened, is a pinion 191 in mesh with the segment 190. 1

The segment 190 has a slot 19 2'which re ceives a roller 193 mounted onthe common actuator 77. 7

As the common actuator 77 is rocked in counter-clockwise direction bythe depression of a'key, the roller 193, acting on the lower face of theslot 192, ro thresegment 190 clockwise againstthe tension of aspring194, one end of which is connected to a studpro jecting from the segment190. j

The clockwise movement of the segment 190 rotates the pinion 191, shaft161, and the tension and ejector rollers 75, in counter- I clockwisedirection, but as the rollers 75 are held away from the stationaryrollers 165 as sociated with the rollers 7 5 110 movement is impartedtothe receipt paper at this time.

As the common actuator 77 reaches the limit of its counter-clockwisemovement, the tension cam 168 rocks the bell crank 180 clockwise, andthe spring 177 causes the stud 174 to follow the arm 176 of said bellcrank-180,.

thus rocking the arm 172 clockwise, which rocks the arms 171, 162 and163 counter-clockwise to engage the rollers 75 with the rollers Sincethe arms- 162 and 163 pivot on the same rod 164 upon which the segment190 pivots, the pinion 191 merely rolls over the segment 190 during theengaging movement of the rollers. 75. To insure that "the paper shall befirmly gripped between the rollers 75 and 165, the cam 168 ismade so "asto move the bell crank 180 far enough to cause the arm 76 thereof tomove away from the stud 174 after the rollers 75 have'been moveddownwardly.

As the common actuator 77 is moved clockwise with the key coupler45 whenthe latter returns to its normal position, the roller 193,

ment 190 counter-clockwise, thus turningthe pinion 191, shaft 161, andthe tension and ejector rollers 75 clockwise tofeed the printed receiptfrom the machine. After the printed receipt has been so fed, and as thev common actuator 77 arrives at its normal position, the low portion ofthe cam 168 is again opposite the roller 178, thus permitting thesprings 167 and 169 to again raise the arms the rollers 165 V vSeueringmeciumzlsmv ext-ending arm 203 having an arm 204 (Figs.

3'and 4) formed at right angles thereto and forked to receive a stud 205projecting from the knife blade 76. This connection 205 with the arm 204accommodates manual opening ofthe knife for threading a new receiptpaper web into the machine. The

I knife blade'pivots on a support stud 206 projecting from a bracket 207secured to an ear 208 of the printer frame 70. 1 Upon'thecounter-clockwise movement of the common actuator 77 the bell crank201 is rocked clockwise by the link 200 to raisethe arms 203 and 204 torock the knifeblade 76 in counter-clockwise direction. As the knifeblade 76 reaches the limit of its counterclockwise movement,which iswhen the limit of the counter-clockwise, movement of the.

common actuator 77 is reached, a retaining pawl 209 urgedin clockwisedirection by a spring 210 engages a shoulder 211 of the knife blade 76to retain the same in its opened position, the forked arm 204 returningto it-s normal vpositlon w th the return movement pr the. commonactuator 77. v

together with the spring 194, rocks the seg- 9 162and 163 to move therollers 75 away from I printed receipt is advanced to the full eX- tentof its movement, the retaming pawl 209 is released by an arm 215 (Figs.1, 3 and 4) secured to the side of the segment 190 when the segment 190.arrives at its normal position, at which time the receipt paper willhave been advanced to its full extent of movement;

A stud 216'. (Figs. 3 and 4;) of. the retaining pawl 209 projectsthrough a slot in the bracket 207 and lies in the path of an car 217 ofthe arm 215.

As the common actuator and the segment 190 reach their normal positions,the car 217 contacts the stud 216 of the retaining pawl 209, and lowersthe stud 216 until the pawl 209 is released from the shoulder 211 of theknife blade ,76, whereupon a spring 218, which was tensioned when theblade was rocked counter-clockwise, rocks the blade clockwise toeffect ashearing action against the side of a stationary blade 215, thussevering the printed receipt from the strip. The receipt is depositedupon the table 152. The downward movement of the stud 216 is stopped bythe bottom of the slot through which it projects.

The spring 218 (Fig. 4) is connected to the stud 205 of the knife blade76 and-to a stud 219mounted in a flange of the printer frame 70. Acompression spring 220 (Fig. mounted on the support stud 206 tensionsthe knife blade 76 against the side of the stationary blade 221 toinsure positive shearing.

Oonsccnticc number printing By referring to Fig. 8, it can be seen thatthe receipt has printed thereon a consecutive number and the date at thebottom, and also a number in line with and to the right of the amount,which number can be used for any designating purpose.

The consecutive number mechanism includes a plurality of type wheels 230(Fig. 5) loose on the consecutive number shaft 166, each wheel having aratchet 229 secured to its side.

A differentially tined pawl 23]. is pivoted to a consecutive numberoperating arm 232 secured to the shaft 202 which is rocked by the commonactuator 77 through the link 200 and the bell crank 201, as previouslydescribed. The counter-clockwise movement ofthe shaft 202, during eachoperation of the machine, raises the pawl 231 to operate the properratchet or ratchets 229 to advance the consecutive number wheel orwheels 230 one step on each operation of the machine in a manner wellknown in the art.

A knob (not'shown) secured. to the end of the consecutive number shaft166 is provided to reset the consecutive number wheels to Zero.

By giving the knob (not shown) one complete turn a spline cut in theshaft eooperates with a pawl (not shown) mounted on each wheel, to turnthe wheels to their zero positions, in a manner also old and well knownin the art.

Date printing Date printing wheels (not shown) also mounted on theconsecutive number shaft 166 are adjusted by knobs (not shown) connectedto one end of tubes 233 (Fig. 6) in an old and well known manner to setup the proper date.

Clerk's type setting A lever234 (Figs. 1, 6 and 11) is provided toadjust a printing wheel 228, which may be used to'designate clerks, oranything else desirable:

Any movement of the lever 23 1 adjusts a printingwheel on the receiptprinting line, and acorresponding wheel on the record strip printingline.

he lever 23 i (Fig. 6) is connected to a tube 235 surrounding the datesetting tubes 233. The-tube 235 has connected thereto a segment 236meshing with a pinion 237 secured to the side of the clerks ordesignating number type wheel 228.

A slot 238 of the segment 236, into which astud 239 projects from theauxiliary frame 96, limits the movement of the segment 236 and the lever234.

An indexing plate 240 (Fig. 11) mounted tothe left of the receipt tableinforms the operator of the machine the number that is set in theprinting position.

The clerks or designating number is also printedupon the recordstrip-retained in the machine. Andto accomplish such printing the typewheel 228 (Fig. 6) carries a pinion 227 meshing with an intermediategear 226 on the shaft 95. The gear 26 drives a gear 225 secured to atype wheel 22a in axial alignment with the amount type wheels 72 whichprint on the record strip.

Check and record strip The check is shown in Fig. 8, and a portion ofthe record strip as printed by this machine, is shown in Fig. 9. The toprow of printing on the check represents the amount and the clerks ordesignating number. The next three lines are printed by the electro, andmay have anything the merchant desires. The last line" represents theconsecutive number of the ticket and the date.

' The three left-hand columns of figures shown'on the record strip inFig. 9, repre sent the amounts, and the right-hand column of figuresrepresents-the clerks or designating number. The dollar typewheel issomewhat wider than the other type wheels, and carries the decimalpoint, the characters 1 to 9, and the dollar sign opposite eachcharacter, but there is no Zero character-the dollar sign beingcentralized at the zero position, thus giving the effect shown in Fig.'9 that is, when the amount does not equal one dollar, the'dollar signsare close to the decimal point, but when the dollar wheel is moved pastits zero position, as is shown in twov instances, the dollar sign is outof line with the other dollar signs printed when the amount does notregister up toSBLOO.

. Type wheel alz'g 'ners An aligner (not shown) correctly holds theconsecutive number type wheels 230' (Fig. 5) and the date wheels (notshown) injtheir adjusted positions.

The amount type wheels 72 and the clerks or designating number typewheels 224 and 228 are aligned by pawls 245 (Fig. 5) operated by the keycoupler 45. The aligning pawls 245, there being one for each amount typewheel, pivot on astud 246 extending b etween the printer frame 7 O andthe auxiliary frame 96, and are held in their proper lateral positionsby a" guide plate 247 secured to a yoke 248 connecting two arms 249(only one of which is shown). The plate 247 is slotted to receive andguide theupper ends of the pawls 245. V V n A spring 250 associated witheach pawl 245 holds arearwardly extending finger 251 ofthe pawl. 245 incontact with a flange 252 projecting from the guide plate 247.

A tension operating plate 253 pivoted on the stud 95 is provided with anotch to receive .anupwardly extending finger 254 of an arm 255 pivotedon a downwardly extending arm of a bracket 256 secured to the keycoupler 45. The plate 253 is provided with an car 257 adapted to rockthe aligning pawls 245 into cooperative relation with the intermediategears 94 and 226, by acting on a surface 258 of an extension 259 of thearm 249.

When the key coupler 45 is rocked counterclockwise upon the downwardmovement of a key, theiarrn 255 is rocked counter-clockwise and thefinger 254 rocks the tension op erating plate 253 clockwise, whereuponthe ear 257 wipes over the surface 258 of the arm 259. Dueto the contourof the surface 258, the armf259 and the arms 249 connected by theyoke248are rocked, counter-clockwise, thus moving the aligning pawls 245into engagement with the intermediate gears 94 and p to align the typewheels. i

h. stud265 (Fig, 5) projecting from the printer frame limits theclockwise movement of the plate 253.

The arm 255 is held rigid with the'bracket 256 by a screw 266 whichprojects through a slot in the bracket 256, but said arm'255 may beadjusted relative to the bracket 256 v to accommodate variations inmanufacture, so that the time of aligning the type wheels can varyaccordingly.

The return movement of the key coupler to its normal position removesthe ear 257-from the surface 259, whereupon the arm 259, together withthe arms 249 and paWls 245, rock clockwise, by gravity, about the stud246 to permit rotation of the intermediate gears 94 and 226 during thedownward movement of the key on a subsequent operation. A stud 267projecting from the printer frame 7 0 into the path of the arm 259limits the clockwise movement of the pawls 245.

, V [viking ribbon The ink ribbon 27 0 (Fig. 6) is fed around an inkingroll 271 loose on a stud. 272 projecting between the printer frame 7 Oand an ink ribbon frame 273. The-ribbon then passes under a tension roll274 around guide studs 275 and 27 6 and around a ribbon guard 277.

The tension roll 274 is supported by a pair of arms pivoted on the stud272. The weight of the roll 274 tensions the ink ribbon 270.

. The common actuator 77 also advances the ink. ribbon one step duringeach operation of the machine. I

A feeding pawl 280 (Fig. 8) supported by a downwardly extending arm (notshown) secured to the consecutive number shaft 202, is held incooperative relation with a ratchet wheel 281 of the ink roll 271 by aspring 278 connected between the feed pawl 280 and a retaining pawl 279, and is moved forwardly on each operation of the consecutive numbershaft 202 to advance the ink ribbon 27 0 to present freshly inkedsections thereof beneath the printing platens. 7

Operation Briefly. the depression of a key rocks the key coupler 45 andthe common actuator 77 counter-clockwise which advances the recordstrip, retracts the hammers, cocks the segment 190 for feeding theprinted receipt, cooks the severing blade 76, advances the consecutivenumber printing wheels one step, advances the ink ribbon to present afreshly inked portion thereof beneath the platens, and releases theretracted hammers when the common actuator 77 reaches the limit of itscounter-clockwise movement, making an impression on the record stripretained within the machine, and printing the receipt which is to behanded to the customer.

Upon the return movement of the key coupler and common actuator 77 totheir normal positions, theprinted receipt is fed from the machine andthe retaining pawl which holds the blade in its cocked position istripped by the arm 215 of the segment 190 on the return of the latter toits normal position, whereupon the blade 76 severs the check or receiptfrom the strip.
